Taking fish oil capsules during pregnancy may protect your baby from eczema.

Scientists believe that Omegap-3 fatty acids passed on via the placenta, affect the unborn baby's immune system which protects against eczema.
Lead author of the study Maria Makrides said, "The fatty acids of the oil may get incorporated into cell membranes inside the fetus, where they dampen down the inflammation that leads to allergies and eczema."
